    Assume that the acceleration of gravity is 10 m/s2 downward, and
    that all friction effects can be neglected. A ball is thrown upward
    at a velocity of 20 m/s. What is its velocity at t = 2 s?
    zero

    a. 10 m/s upward
    b. 10 m/s downward
    c. 20 m/s downward
    d. 20 m/s upward
